Today Katie Price has announced that she’s divorcing the father of her 8-month-old baby Jett, and unborn child.

She tweeted: “Sorry to say me and kieran are divorcing..."

She alleged that Kieran had been having a "full blown sexual affair" with one of her best friends for the past 7 months.

She added: “Kieran is a disgusting human being doing this after I've just had a baby... and still doing it till I caught them”

While it's not been possible to verify Katie's allegations, the mum-of-4 was clearly in distress as she tweeted: “No human being deserves this especially being 6 months pregnant"

“Worse pain in the world”

Katie alleges that Kieran, 25, was having an affair with her friend Jane Pountney, 49, who was a maid of honour at the couple’s wedding in January 2013. Jane, who is married herself, was also at Katie's wedding to Alex Reid.

After sending her tweets, Katie and Keiran turned up at Jane's house in Hove, where Katie clearly wanted to confront her friend and find out the truth. About 40 minutes later, Keiran left with a friend, leaving Katie inside with Jane.

Katie has since released a heartfelt statement on her website, which reads:

"I appreciate most people will have seen my tweets on the subject of my marriage to Kieran.

"I make no apologies for them though it will be appreciated that, sending them immediately after Kieran confirmed to me what he had been doing for the last 7 months, those tweets were a sign of my heart breaking. That he was doing it with a close friend of nearly 20 years is hard to understand.

"This statement however is from my head, not my heart. I am appalled that someone I loved, trusted and believed in has behaved in this way. If he had so little respect for our relationship I would have hoped he would have thought about our child or the one that we have on the way. That he did not means he will no longer be part of my life. I will do all I can to ensure he maintains a relationship with his children should he want that.

"I am so grateful for the love of my children and family at this time."

This will be Katie’s third divorce, and we can only imagine the strain she's feeling as she continues to care for her 4 children while preparing for the birth of her 5th.
